Hello All,
I have been encountering a problem when trying to boot the Android GingerBread 2.3 SDK 2.0 pre-built kernel and rootfs image when using an initramfs.
In my boot scanario i am using tftp to transfer both the kernel image and the root file system as an initramfs archive. However although the kernel appears to start successfully the graphics kernel modules do not load and the android init process enters loop, see the console output attached. insmod for vpss appears to fail, but it is not clear why this should be the case as the kernel and rootfs are unchanged from the versions that I can successfully boot on an SD card or using NFS. Volatile storage is not an option in my application.
I have not modified the image apart from packaging it as an initramfs archive using:
find . -print0 | cpio --null -ov --format=newc | gzip -9 > ../initramdisk.gz
mkimage -A arm -T ramdisk -n 'Ramdisk' -C none -d initramdisk.gz initramfs.img
The u-boot kernel bootargs are:
console=ttyO2,115200n8 rootwait androidboot.console=ttyO2 rw earlyprintk mem=166M@0x80000000 mem=768M@0x90000000
and the boot script:
dhcp; tftpboot 0x9125F820 /srv/tftpboot/initramfs.img; tftpboot 0x91000000 /srv/tftpboot/androidimage; bootm 0x91000000 0x9125F820
where androidimage is the uImage from the SDK pre-built kernel image. I have tried moving the initial load addresses of the images without success.
I would be grateful if anyone has successfully booted with this approach, or any pointer as to where I might be going wrong.
Thanks.
